18 Jaclyn experiments with dilations of lines and makes the following claim.

A dilation of scale factor 2 with center of dilation (3, 0) will result in a line that is parallel to, and
distinct from, the original line.
Which of the following options best describes Jaclyn's claim?

Jaclyn is incorrect since lines passing through the origin will remain the same.
Jaclyn is correct since any dilation will take a given line to a distinct parallel line.
Jaclyn is incorrect since lines passing through the center of dilation will remain unchanged.
Jaclyn is correct since any line will be taken to a distinct parallel line after the given dilation.

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

wait this depends wether emily and zach how they are thinking.

yes they are the same.

  or  

sin y = 7/q

7 is the opposite side length, q is the hypotenuse

tan y = 7/r

7 is the opposite side length, r is the adjacent side length

using sohcahtoa ^^^^

cos y = adjacent/hypotenuse

cos y = r/q
